摘要：
A new species of Rhyacoglanis is described from the rapids of Jatobal, Para State, Brazil. This species differs from the congeners by fusing hypurals 3, 4, and 5 (vs. hypural 5 free). It also differs from the other species, except for Rhyacoglanis epiblepsis, by the color pattern with numerous dark spots on the body, short postcleithral process, rounded pectoral and caudal fins, and incomplete lateral line. This species is known only from the type locality, which is currently flooded by the Tucurui reservoir.
